Universal Windows Platform

Welcome to the Windows Platform Developer (WPDev) Feedback site. This feedback forum provides the WPDev community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center Store (developer portal, back-end services, reporting/analytics and process)
  • Windows Stores (Windows and Windows Phone)

Your suggestions will be reviewed by the Windows platform developer team, providing feedback to help with planning ideas and to better understand how developers are using the development platform.

What this forum is not intended to cover or capture:

If you’re new to this whole UserVoice thing, we’d like to note two important things about this site: (a) List items (and item rankings) represent community interest in features, and does not represent an actual priority list for the product team; and (b) Suggestions made using this forum will be moderated if they do not actually represent a feature request.

How can we improve the Windows dev platform?

  1. Theme aware Splash Screen Images

    I like the functinality of the SplashScreenImage.jpg file, but it's too limited for what I'm trying to do. At a minimum I need to have 2 images that are auto selected based on the phone's current theme. SplashScreenImageLight and SplashScreenImageDark would be great!

    After that, it would be great to have the option to select an image from IsolatedStorage so that my app can update its splash screen image as needed.

      • Remove silverlight and move foward to WinRT as sole platform

        Going foward, it makes sense to use WinRT including WinRT XAML as the UI Framework and base foundation of Windows Phone. Old Silverlight Apps should still be supported so our investments are save but new applications should only be created with the new Platform. Alternatively, provide both and let developers decide which Platform to choose.

        • {x:Static NumericConstant} way of accessing constants in XAML page

          The "{x:Static NumericConstant}" way of accessing code page constants in XAML page already exists in WPF. This approach will provide an elegant way of accessing constants both in code and XAML pages in Silverlight, and for my immediate need in Windows Phone 7. For instance,

          public partial class App : Application
          {
          public const int ImageHeight= 173;

          ...
          }

          in App.xaml.cs

          and accessing the constant ImageHeight in a XAML page as:

          <Image Height="{x:Static App.ImageHeight}" ...

          is a neater way of coding as compared to alternative approaches.
          Please please incorporate this in future release.

          • PictureDecoder that handles PNGs and can run on any thread

            As for now the PictureDecoder can only decode JPG and run on the UI thread.

            I am especially thinking about tile generation on background agents : I'd like to have an enriched PictureDecoder able to run on any thread and decode PNG as well.

            • Silverlight layout performance

              The biggest problem I almost exclusively run into when working on WP7 apps is the layout performance of Silverlight. It's takes quite some effort to work around that problem. And according to web searches about this problem I felt that I'm not a lone with this. It'd be great if you would work on a solution to improve the situation.

              • Implement XAML style triggers

                Hi! Please implement style triggers for Windows Phone XAML (BAML?). Sometimes they're much more useful than data binding (for example, when I need a StaticResource as a property value).

                • Support bulleted paragraphs with RichTextBox

                  It is impossible to manage even a hanging indent because Paragraph lacks Margin and TextIndent properties. However, hacking a hanging indent is not the real goal - general support for bulleting.

                  Build support for bullets and numbering into the Paragraph class with properties something like this

                  NumberStart int, -1 = inherit from previous run
                  NumberStyle enum {None, Bullet, Arabic, Letter, Roman}
                  NumberFlags enum flags {UpperCase, DottedLevels}
                  NumberLevel int

                  Make NumberStyle default to None and all this is non-breaking.

                  • Avoid the need of ID_CAP_CAMERA when using audiosink

                    Now in SDK 7.1 it is possible to record audio by using the AudioSink Silverligh class, so we don't need to trick the system by using the XNA loop, but when using this class the tag <Capability Name="ID_CAP_CAMERA"/> should be present at WMAppManifest.xml file, but we are only using microphone.

                    • ensure theme resources are switched when resuming app

                      There's one area where Mango is a retrograde step when compared with NoDo : theme support.

                      In NoDo the user could leave the app switch the theme (i.e. Dark or Light) & return to the app which would now, in theory, respect their selection.

                      In Mango the user's faced with an unholy mess because the app is only informed of the system's theme state at start-up.

                      Developers have the choice of looking incompetent or ruthlessly picking a theme & sticking to it, thus rendering the ability to choose an overall theme pointless.

                      • Please enable HttpWebRequest.AllowWriteStreamBuffering

                        Without this being enabled, an app can run out of memory pretty quick when transmitting large data using HttpWebRequest.

                          AS developing XNA apps in Windows Phone 8 development will not be supported anymore , we sometimes need to have 3d Models and work with them inside application without need to learn C++ & Direct X which will take alot of time and maybe valuable for game developers only .

                          so we need aupport for such feature in XAML Code like in SilverLight 5

                              Better support for Commands for all controls, allowing to bind a Command in the ViewModel to any event from a supported control in XAML, without having to use third party tools such as MVVM Light. (no offense MVVM Light ;) )

                                  • Include TextBox.IsSpellCheckEnabledProperty property and TextBox.IsTextPredictionEnabled property in Windows Phone Silverlight Apps.

                                    Just like in WinRT, could we have Spell Checking options and Text Prediction in Window Phone Silverlight apps.

                                      • WP8.1 Disable Fast Resume

                                        Hoello, with WP8.1 the Silverlight XAP apps are forced to use "Fast Resume". This has broken my app Swipe Tunes as I hastilly submitted a WP8.1 update with Transparent Tile and realised later that fast resume was causing issues with my secondary tiles etc.

                                        Fast resume has pretty much killed my app and I can't delete the WP8.1 XAP from the store, and as such it looks like my app will not be able to go back on the WP Store or if it does it will have to be under a new name and abandon previous customers.

                                        Please cant…
